Application filed September 9, 1916. Ser al N 0. 119,186.

To all whom it may concern: 1

Be it known that I, HUGO MOCK, a citizen of the United States ofAmerica, residing at New Brighton, in the county of Richmond and Stateof New York, have invented certain new and useful Improvements inCollapsible Containers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

I This invention relates to collapsible containers, and moreparticularly to that type commonly used for pastes or other plasticsubstance.

It has for an object to provide an efficient container which may be mademost economically, being formed of a metal which may be stamped to thedesired shape, after which the edges may be locked together as by theusual seams for tin or other boxes.

A further object of this invention is to provide a container of aflexible metal having demarcations formed therein, along lljvhlth theparts of the container may easily 'A further object is the provision ofacontainer of simple formation having an outlet formed in a part of theshell within the general lines of the container.

Further objects will be apparent from the following specification,appended claims, and drawings, in which,

Figure 1 is a perspective view of one form of container,

' Fig. 2 is a side elevation thereof, showing parts broken away forclearness,

Fig. 3 is a cross sectional view as on the line 33 of Fig. 2,

Fig. 4 is an enlarged sectional view showing the demarcation betweenthe-symmetrical side sections,

Fig. 5 shows the container with an end outlet, and,

Fig. 6 shows a cross sectional view of a container of elliptic crosssection.

This invention provides for the packing of substances in a paste orplastic form, where a cheap container is necessary, and

ilong with its economical features, it pernits a more rigid containerbeing had, which at the same time possesses the necassary flexibility topermit its being com- )ressed or collapsed. It may be made of anydesired meta but preferably of a very thin gage of tin or tinned sheetiron and will be of any desired cross sectional configuration which hassymmetric portions, to permit lines of demarcation being formed in themetal, so that when the container is compressed, the weakened lines willallow easy collapse of the container.

Referring to the drawings in which the several characteristic featuresare shown, 10 indicates a container having panel sections 11 for theside walls, and these panel sections are separated by the lines ofdemarcation 12, which may be lines formed by deep scoring. The edges ofthe blankcomprising the side walls may be secured together as by theusual double lap seam 13. The ends of the container may be of reducedproportions by having the tapering faces 14, which may also have theedges sealed as by the seams 15. One of these sections 14 may have thenipple 16 formed therein as by pressing the metal into that form, andthis nipple may receive the cap 17 which will be held thereon byfrictional contact.

In Fig. 5, the container 18 has the seam 19 to seal the edges, and thetapering faces 20, which in being formed as by stamping, will have thecomplemental portions 21, which, when the seams 22 are formed, willproduce an outlet from the container through the end.

Fig. 6 is to show the possibility of using any symmetrical cross sectionand in this view, 23 is a container having the seam 24, and at desiredpoints, dependent. on where the lines of fold will occur, the metal isscored as at 25 to weaken the metal and to permit the container to becollapsed along definite lines.

It is evident from the foregoing that by the use of a very thin gage ofmetal, a container maybe made which although more rigid than the usualform of drawn tin tube commonly used, is sufficiently flexible to permitits being collapsed to eject the plastic contents thereof, and asdefinite lines of fold and bending of the side walls are formed, it isapparent that practically the entire contents may be ejected.Furthermore, the container may be made by stamping a blank of a desiredshape, after which said blank may be folded, when the open edges may belapped or otherwise secured together.

The drawings are submitted for illustrative' purposes only and imply nolimitation to the number of forms in which the container may be made,nor does the specification limit the material used.

It is evident that the object of this inven-- may be used. It will benoticed that theweakening lines appear in opposite halves of thecontainer so that in ejecting the contents,

the container is gradually collapsed to permit the expulsion of theentire contents of the container. 4

Having" thus described this invention, I claim 1. A collapsiblecontainer of thin sheet metal, of substantially elliptical sha e andhaving axial weakening lines scored t ereon.

2, A container of comparatively rigid sheetmetal having areas thereonthinner than the metal of which the body of said container is composedso as to permit the flattening of said container along said weakeningareas.

3. A container of relatively rigid sheet metal having a length greaterthan its width, the surface of said container being divided into aseries of panels by scoring so as to permit the compression of saidcontainer along the lines of said scoring.

41. A container of thin and comparatively rigid sheet metal, the innersurface of which has been scored with a number of weakening lines topermit the compression of the contents of said thereof.

In testimony whereof I aflix my signature.

HUGO MOCK.
